" I am not suggesting that history or scepticism by themselves can provide all the answers to all these questions. History, after all, is not a forward-looking discipline. It can only tell us what happened the last time, not what will happen next time. Similarly, scepticism is hardly sufficient to do anything but ask questions. But together they—history and scepticism—form a potent force for enquiry. "
